p-Toluene sulfonamide was used to prepare the precursor required for synthesis of ethyl 6-phenyl-1-tosyl-1,2,5,6-tetrahydropyridine-3-carboxylate. It act as a derivative of ammonia activated to alkylation by alkyl halides is exemplified by the synthesis of N-tosyl-2,3-dihydroisoindole from o-xylylene dibromide. It is a precursor of N-tosyl imines.
